Abstract
Description
Technical Field
[0001] This invention relates to the technical field of emergency management systems, and more specifically, to a smart station emergency joint defense system. Background Technology
[0002] Traditional station monitoring relies on manual shifts, making it prone to oversights due to visual fatigue. Smart stations, building upon existing digital and intelligent stations, fully leverage next-generation technologies such as artificial intelligence, big data, cloud computing, AIoT, and digital twins. They provide passengers with a comprehensive experience, offer intelligent operation and maintenance data support, provide panoramic control for station operations, and offer decision support for management. This achieves safer operations, smarter services, and more efficient management by developing a smart system encompassing five key areas: holographic perception, intelligent analysis, panoramic control, precision and convenience, and proactive evolution.
[0003] However, existing smart stations also have problems such as isolated operation of subsystems such as fire protection and medical care, reliance on manual dispatch for linkage, slow sensor response, and various coordination defects. Based on the above problems, we have provided a smart station emergency joint defense system. Summary of the Invention
[0004] To address the problems mentioned in the background section, this invention provides an intelligent station emergency joint defense system.
[0005] The intelligent station emergency joint defense system provided by this invention adopts the following technical solution: The intelligent station emergency response system includes: The multi-camera collaborative positioning module consists of distributed high-definition positioning cameras, which use visual algorithms to achieve seamless cross-regional tracking and three-dimensional coordinate positioning of targets. The AI video analysis module uses deep learning algorithms to identify abnormal behaviors such as falls, gatherings, and leaving items behind by people in the station in real time, and outputs the type of abnormal behavior and the coordinates of its occurrence. The emergency response module includes a digital emergency plan library, which automatically triggers associated fire alarms, power control, and evacuation guidance linkage operations when responding to abnormal events. The data security module uses AES-256 (Advanced Encryption Standard - with 256-bit key) encryption technology to encrypt and store personnel information, and sets up a 24-hour automatic deletion mechanism based on timestamps.
[0006] Preferably, the multi-camera collaborative positioning module includes an infrared thermal imaging unit, which continuously tracks the target through thermal radiation characteristics in low-light environments, with a thermal imaging resolution of 384×288 pixels. It can also add a multispectral fusion algorithm to combine data from multiple sensors such as visible light, infrared, and lidar to improve the robustness of target recognition.
[0007] Preferably, the multi-camera collaborative positioning module further includes a trajectory prediction unit, which predicts potentially dangerous behaviors by analyzing personnel movement paths.
[0008] Preferably, the AI video analysis module integrates an occlusion compensation algorithm, which enables continuous tracking when the target is occluded through spatiotemporal context association. The specific steps are as follows: 1) Video surveillance detects that the target is occluded, and predicts the target's trajectory through spatiotemporal context modeling; 2) The UWB positioning module continuously provides the coordinates of anchor points in the surrounding environment, and uses the Kalman filter algorithm to fuse visual prediction results with real-time UWB data; 3) Generate a compensated continuous coordinate flow.
[0009] Preferably, the emergency response module includes a medical emergency submodule and a fire response submodule. The medical emergency submodule automatically obtains the coordinates of the nearest AED device through UWB positioning technology and directly connects to the hospital's emergency department. The specific steps are as follows: 1) When abnormal behaviors such as falls are detected, a health data request is triggered, and the passenger's identity identifier is quickly read through RFID / NFC tags; 2) Blockchain nodes verify identity and permissions, based on the Hyperledger-Fabric channel isolation mechanism, and smart contracts are automatically approved: rescue personnel need to pass two-factor authentication; 3) Decrypt and push health information; data transmission uses TLS 1.3 + SM4 encryption (Chinese national standard). 4) After the emergency response is completed, the event record is written to the blockchain, which includes timestamp, location coordinates, data summary, and response result.
[0010] Preferably, the fire-fighting submodule includes a lidar fire source location unit, which can generate three-dimensional fire data and link with the fire pipeline control module. After a fire occurs, it automatically shuts off the power in the fire area and generates three-dimensional fire location data.
[0011] Preferably, it also includes a special passenger service module, which contains a biometric comparison unit that matches the identity information of special passengers through facial recognition.
[0012] In summary, the present invention has the following beneficial technical effects: 1. This application adds a cross-domain technology integration of "occlusion compensation algorithm + UWB positioning + blockchain health data" to maintain good tracking continuity in complex scenarios such as occlusion and low light. By using a high-definition positioning camera equipped with AI vision algorithm, it can track the movement trajectory of people in the station in real time; it significantly improves the target tracking continuity in complex environments. By using an occlusion compensation algorithm combined with UWB positioning technology, it can achieve continuous tracking through motion trajectory prediction when the target is completely occluded by luggage or crowds.
[0013] 2. This application introduces a multimodal perception system of "thermal imaging tracking + three-dimensional fire modeling". When a fire is caused by an electrical short circuit, the system automatically triggers the "fire plan", simultaneously activating the fire alarm throughout the station, shutting off the power in the fire area, sending the precise fire location to the fire department, and guiding the intelligent signs in the station to switch evacuation routes to quickly evacuate the public.
[0014] 3. In this application, by actively capturing abnormal passenger behavior, even if a passenger loses consciousness and is unable to call for help, the system can detect the abnormality immediately, display the specific location in real time, and immediately initiate rescue, achieving "responding before being called". While issuing an early warning, the system will also push the passenger's medical history information in real time, so that rescuers can have a more comprehensive understanding of the situation and take targeted emergency measures, avoiding the impact of missing information on the treatment effect. Compared with traditional indiscriminate rescue, it is more accurate and efficient. Attached Figure Description

[0019] Preferably, the multi-camera collaborative positioning module includes an infrared thermal imaging unit, which continuously tracks the target through thermal radiation characteristics in low-light environments, with a thermal imaging resolution of 384×288 pixels. It can also add a multispectral fusion algorithm to combine data from multiple sensors such as visible light, infrared, and lidar to improve the robustness of target recognition.
[0020] Preferably, the multi-camera collaborative positioning module further includes a trajectory prediction unit, which predicts potentially dangerous behaviors by analyzing personnel movement paths.
[0021] Preferably, the AI video analysis module integrates an occlusion compensation algorithm, which enables continuous tracking when the target is occluded through spatiotemporal context association. The specific steps are as follows: 1) Video surveillance detects that the target is occluded, and predicts the target's trajectory through spatiotemporal context modeling; 2) The UWB positioning module continuously provides the coordinates of anchor points in the surrounding environment, and uses the Kalman filter algorithm to fuse visual prediction results with real-time UWB data; 3) Generate a compensated continuous coordinate flow.
[0022] Preferably, the emergency response module includes a medical emergency submodule and a fire response submodule. The medical emergency submodule automatically obtains the coordinates of the nearest AED device through UWB positioning technology and directly connects to the hospital's emergency department, with a positioning error ≤ 0.5 meters. The specific steps are as follows: 1) When abnormal behaviors such as falls are detected, a health data request is triggered, and the passenger's identity identifier is quickly read through RFID / NFC tags; 2) Blockchain nodes verify identity and permissions, based on the Hyperledger-Fabric channel isolation mechanism, and smart contracts are automatically approved: rescue personnel need to pass two-factor authentication; 3) Decrypt and push health information. Data transmission uses TLS1.3 + national standard SM4 encryption, with a latency of ≤500ms; 4) After the emergency response is completed, the event record is written to the blockchain, which includes timestamp, location coordinates, data summary, and response result.
[0023] Preferably, the fire-fighting submodule includes a lidar fire source location unit, which can generate three-dimensional fire data and link with the fire pipeline control module. The fire location accuracy reaches ±15°. After a fire occurs, it automatically shuts off the power in the fire area and generates three-dimensional fire location data.
[0024] Preferably, it also includes a special passenger service module, which contains a biometric comparison unit that matches the identity information of special passengers through facial recognition.
[0025] Example 1 Taking a passenger fainting in a waiting hall as an example, high-definition positioning cameras distributed throughout the station hall continuously capture images of the waiting hall. An AI video analysis module identifies the fainting passenger and determines their posture by detecting key points on the body, such as the head, shoulders, elbows, and knees. When an abnormal posture, such as falling or lying flat, is detected and there is no significant movement for a period of time, an alert is triggered. Visual algorithms achieve seamless cross-area tracking and three-dimensional coordinate positioning of the target, outputting the type of abnormal behavior and its coordinates. Then, a health data request is triggered, quickly reading the passenger's identification identifier via RFID tags and confirming the passenger's identity through a biometric comparison unit. Next, the coordinates of the nearest AED device are automatically obtained through UWB positioning technology and directly connected to the hospital emergency department to contact rescue personnel. Based on the Hyperledger-Fabric channel isolation mechanism, the smart contract automatically approves the application and performs two-factor authentication on the rescue personnel by recognizing their facial features and identification badge information. Subsequently, the passenger information is decrypted to understand the passenger's past chronic disease history, and the data is encrypted using TLS1.3 + national cryptographic SM4 and pushed to the rescue personnel. The rescue personnel can then take emergency measures for the passenger as soon as possible based on the passenger's past medical history. Finally, after the emergency response is completed, the time of the incident, the coordinates of the incident location, the passenger data summary, and the results of the incident response are written into the blockchain record.
[0026] For customers' past medical history information, AES-256 encryption technology is used to encrypt and store personnel information, and a 24-hour automatic deletion mechanism based on timestamps is set up to prevent passenger information from being leaked.
[0027] Example 2 Taking the occlusion of a moving passenger target as an example, high-definition positioning cameras distributed in the station hall generate monitoring information and monitor the passenger's movement path. When the video surveillance detects that the target is occluded, the spatiotemporal context model is built in the LSTM network to predict the target's trajectory. The UWB positioning module continuously provides the coordinates of the surrounding environment anchor points. The Kalman filter algorithm is used to fuse the visual prediction results with the real-time UWB data to generate a compensated continuous coordinate stream. During the monitoring process, if an emergency occurs, such as a passenger fainting or other abnormal behavior, the steps in Example 1 can be repeated to carry out emergency rescue for the passenger. This end-to-end approach from abnormal behavior identification to emergency response reduces delays and enables rapid rescue operations.
[0028] Example 3 Taking a low-light environment at night as an example, high-definition positioning cameras distributed in the station hall generate monitoring information. Due to the low light intensity in the area, the multi-camera collaborative positioning module includes an infrared thermal imaging unit. In low-light environments, the target is continuously tracked through thermal radiation characteristics, with a thermal imaging resolution of 384×288 pixels. Furthermore, a multispectral fusion algorithm can be added, referencing Russian infrared thermal imaging technology, combining data from multiple sensors such as visible light, infrared, and lidar to improve the robustness of target recognition, enhance the clarity of the monitoring video in low-light environments at night, and improve the recognition effect.
[0029] Example 4 Taking a platform fire as an example, high-definition positioning cameras distributed in the station hall generate monitoring information. Through the lidar fire source positioning unit, three-dimensional fire data can be generated and linked with the fire pipeline control module. The UWB positioning module continuously provides the coordinates of anchor points in the surrounding environment. By using the Kalman filter algorithm to fuse visual prediction results with UWB real-time data, the fire positioning accuracy reaches ±15°. After the fire occurs, the power supply in the fire area is automatically turned off and three-dimensional fire positioning data is generated.
[0030] The above embodiments can be applied not only to emergency response management within stations, but also to other locations requiring coordinated management, such as schools, shopping malls, and subways. By proactively capturing abnormal passenger behavior, even if a passenger is unconscious and unable to call for help, the system can detect the abnormality immediately, display the specific location, and initiate rescue immediately, achieving "preemptive response." Furthermore, while issuing an early warning, the system will simultaneously push the passenger's medical history information, allowing rescue personnel to have a more comprehensive understanding of the situation and take targeted emergency measures, avoiding the impact of missing information on treatment effectiveness. Compared to traditional indiscriminate rescue, this approach is more precise and efficient.
